Description: At the Marsh Creek area, you can see large numbers of migrating waterfowl, especially Northern Pintail. Both Tundra and Trumpeter Swans can be seen during migration. Sandhill Crane breed at Marsh Creek, and occasionally American White Pelican can be seen loafing. A Golden Eagle pair nests regularly on the cliffs east of the highway at Red Rock Pass. Watch also for nesting White-throated Swift and Violet-green Swallow on the cliffs. Peregrine Falcon have been seen in the area, though nesting has not been confirmed.
